An electric current can have no current when the switch is OPEN
The arrows around the positive point charge illustrates the direction of the electric force/field.
<h3>What is Electric field?</h3>
This is described as an area in which force is exerted om other charged particles or objects.
Arrows could be around the positive or negative point charge and helps to depict the direction of the electric force.

Answer:
Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
